Most Helpful Girl
I would say it if the guy was an a**hole. I wouldn't say it to a guy just because he was ugly. If his personality sucked because he was just boring or nerdy, nah I wouldn't say that. He'd have to have done or said something mean spirited and nasty to me or someone I care about for me to unleash some venom like that.
I've said something similar to this slimy guy that was trying to get with me. He was really perverted and disrespectful so I let him know what I thought of him.
